A pendulum moves a periodic time “  $\frac{3}{2}$   T ” from rest point ,makes a displacement ………  

The time taken from A to B is ….. The time taken from B to C .

If the frequency is 0.05 Hz, the displacement done in time 30 second starting the motion from B is …….

If the time of a max. displacement is 2 S, so the frequency is ………..

all of the following are units of frequency except ………

If the ratio between the periodic time and the frequency is 625 s², so the time of 3 oscillation is....

if the time taken from “ B” to “ A” is 5 second

Find frequency ……
